Terpenoid-related metabolites from a formosan soft coral Nephthea chabrolii.
Two new sesquiterpenoidal natural products chabrolidiones A and B, two C(18) terpenoid-related carboxylic acids, ketochabrolic acid, and one naphthoquinone derivative chabrolequinone C (5), along with two known compounds (+)-aristolone and teuhetenone A (7) were isolated from a Formosan soft coral Nephthea Chabrolii.
New Sesquiterpenoids and a Diterpenoid from Alpinia oxyphylla
The inhibitory effects of compounds 1–12 on α-glucosidase were evaluated, and compounds 1, 3 and 6 showed moderate bioactive effect, with inhibitory rates of 10.3%, 10.0% and 11.5%, respectively, compared to the positive control acarbose.
Composition of the Essential Oil of Teucrium heterophyllum L'Hér. Grown in the Canary Islands
Abstract A steam distilled oil obtained from the aerial parts of Teucrium heterophyllum L'Her., grown in la Palma, Canary Islands, was analyzed by capillary GC and GC/MS. Fifty nine components were
Sesquiterpenoids from Teucrium ramosissimum.
Structures, Occurrences and Biosynthesis of 11,12,13-Tri-nor-Sesquiterpenes, an Intriguing Class of Bioactive Metabolites
The compounds 11,12,13-tri-nor-sesquiterpenes are degraded sesquiterpenoids which have lost the C3 unit of isopropyl or isopropenyl at C-7 of the sesquiterpene skeleton. The irregular C-backbone
A new sesquiterpene hydroperoxide from the aerial parts ofAster oharai
Phytochemical works on the aerial parts of Aster oharai (Compositae) led to the isolation of a new sesquiterpene hydroperoxide, 7α-hydroperoxy-3, 11-eudesmadiene, and seven known compounds, teucdiol B, α-spinasterol, which showed cytotoxicity against cultured human tumor cell lines in vitro.
Sesquiterpenes from the Saudi Red Sea: Litophyton arboreum with their cytotoxic and antimicrobial activities
A new pseudoguaiane-type sesquiterpene named litopharbol was isolated from the methanolic extract of the Red Sea soft coral Litophyton arboreum and determined on the basis of nuclear magnetic resonance (NMR) spectroscopic data and mass spectrometric analyses.
The role of new eudesmane-type sesquiterpenoid and known eudesmane derivatives from the red alga Laurencia obtusa as potential antifungal–antitumour agents
A new eudesmane sesquiterpenoid, eudesma-4(15),7-diene-5,11-diol (1) along with the known trinor-sesquiterene, teuhetenone (2), and a seco-eudesmane sesquiterpene, chabrolidione B (3), have been
